feat(mobile): hidden connection log panel for device-only diagnostics

Connection lifecycle events (probes, transport failures, resume decisions)
are mirrored into an in-memory trail that resets on every launch. A long
press on the connect-screen logo or the instances list opens a panel that
renders the trail with one-tap copy, so release builds can report the exact
probe sequence without a tethered debugger. Details reuse the already-masked
log payloads — no tokens or secrets are captured.
